3 Claims. 1

The present invention relates to copy-boards for photoengraving andother cameras.

Objects and advantages of the invention will be set forth in parthereinafter and in part will be obvious hereirom, or may be learned bypractice with the invention, the same being realized and attained bymeans of the instrumentalities and combinations pointed out in theappended claims.

The invention consists in the novel parts, constructions, arrangements,combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a parthereof, illustrate one embodiment of the invention, and together withthe description, serve to explain the principles of the invention.

Of the drawings:

Figure 1 is a side elevation with certain parts broken away showing anillustrative and preferred form ofA copy-board for use withphotoengraving cameras;

Figure 2 is a similar view with other parts broken away and showing thecopy-board in position for copying;

Figure 3 is an elevation of the copy-board of the present invention inclosed or printing position; and

Figure' 4 is a fragmentary detailed sectional view taken on the line 4-4of Figure 1.

The present invention has for its object the provision oi a novel andimproved copy-board for holding relatively large copy and which isparticularly useful in connection with photoengraving andphotomechanical cameras. A iurther object of the invention is theprovision oi an improved copy-board which can be easily operated inspite of its relatively heavy construction, and which is convenientlyloaded and unloaded, and may be moved from loading to exposure positionwithout danger of the copy changing its position.

Referring now in detail to the present preferred and illustrativeembodiment of the invention as shown in the accompanying drawings,supporting frames I8 are provided, one at either end of the structure,each frame being provided with a relatively broad heavy base and abearing l2 near the upper part of the frame in which is rotatablyjournalled a pivot shaft I4 projecting laterally from a plate I6 fixedto the side portion of the copy-board. The copy-board itself comprises arigid flat sheet or baseboard 2D of the desired size covered on one facewith a layer 22 of sponge rubber or other suitable resilient material onwhich the material to be copied is laid when the copy-board is open andin the horizontal position shown in Figure 1. Overlying the copysupporting surface of sponge rubber layer 22 is a flat, transparentglass sheet 24 mounted in a surrounding metal frame 26 which is hingedto one edge of the baseboard 20 by hinges 28 so that the glass frame maybe closed tightly against the sponge rubber 22 to smooth and securelyhold the sheet to be copied.

Locking means are provided for locking the glass cover plate 24 in copyretaining position or in copy loading position. For this purpose, a bar30 is pivotally mounted in lug 32 attached to the side of frame 2Bopposite the hinges 28, and extends towards the corresponding edge ofthe baseboard 20. Bar 3U is provided with notches 34 adapted to engagewith a pin 35 supported at each of its ends in a bracket 38 xed to ametal frame 4D surrounding the baseboard 20. As shown in Figure 1 of thedrawing, the bar 30 may be latched with one of the notches 34 over thepin 36 to hold the cover glass 24 in raised position, or the cover glassmay be lowered, and

the other notch 34 in bar 35] may be latched over` the pin 35 to lockthe glass 24 rmly against the sponge rubber sheet 22 with the copybetween the sponge rubber sheet and glass.

Counterbalance means are provided for assisting in raising cover glass24 and for preventing the cover glass from falling rapidly against thesponge rubber sheet 22, if the bar 38 should slip from the oneratorshand. as such a drop might result in breakage of the glass. For thesepurposes brackets 44 are fastened midway along the opposite sides oimetal frame 2t, and are pivotally connected to their respective links46. At the lower end of each link d* is rotatably mounted a roller Pwhich can roll in a snug'y ting guide channel "0 reeurely lrast-ned tonn edge of the baseboard 20. one such guide channel being provided ateach of two opposite sides of the baseboard. Guide channel also servesas the support for plates I6 which are preferably so located that thepivot pins I4 are in axial alignment with the center of mass of theframe. Spring means are provided within each channel 50 and are adaptedto be extended in tension as the cover glass is moved to copy holdingposition. As embodied, such spring means comprise a helically coiledspring 52 having one end anchored to a pin 54 on the interior of channel50, and having its other end attached to a link 56 which is supported onstud 58 serving as the axis oi roller 48 so that the pull of spring 52is applied directly in line with the path of movement of roller 48.

A stop is provided for holding the copy-board in horizontal loadingposition, and comprises the longitudinally extending bar 68 of angularsection which extends from one frame I to the other and is rivetedthereto in position to be engaged by the underside-of channels Silas thecopy-board is moved to horizontal position. VStop means are alsoprovided for holding the copy-board in vertical position, while thematerial is being copied by the camera, and for this purpose onefo'fhthe'tie rods 62 extending between the two frames li! .is so locatedthat it will be engaged bytthe 'back of the channels 563 in the positionshown in FigureZ.

The invention in its broader aspects is not limited to the specicmechanisms-'shoWn-and described but departures may be made therefromother of said copy holding members and linearly ,Inovablezfalong saidchannel member, a pair of Within the scope of the accompanying claimswithout departing from 'the .principles ofthe invention and Withoutsacri'c'ing its chief advantages.
